Morphology and histology of placentas of wild-type, <i>Cul4b</i> heterozygous and absorbed embryos at 14.5 dpc.

Abstract

<p>(A) Representative photographs of placentas of wild-type, <i>Cul4b</i> heterozygous and absorbed embryos at 14.5 dpc. (B) H&E staining of radial sections of placentas. sp, spongiotrophoblast layer; la, labyrinthine layer. Lower panels are the higher magnification of the upper panels. (C) Immunohistochemisty of radial sections of placentas with an antibody to PECAM, an angiogenesis marker. Middle panels are the higher magnification of the upper panels, and lower panels are the higher magnification of the middle panels.</p
